    摘要： A position-data converter and a motor-drive control device are connected. The position-data converter receives two-phase, sine-wave analog signals da and db from two first magnetic detectors, respectively, and converts these signals da and db to position data. On receiving a positioning instruction, the motor-drive control device calculates the value of current, from the current position signal generated by the position-data converter. The permanent magnets incorporated in a linear motor are used as components of a linear scale, as well.

    摘要： In a conventional hybrid scheme used to mount a rechargeable battery in a motor vehicle, store into the battery the electric power that has been obtained via a regenerative brake, and utilize the power during acceleration of the vehicle, when a temperature rise of the battery due to charging or discharging causes a temperature of the battery to stay outside a defined range, it has been absolutely necessary to stop the battery charge or discharge, and fuel efficiency has decreased. This invention predicts a charge level and temperature of a rechargeable battery from the cruising input/output power requirements calculated from route information and historical records of cruising, prevents a stoppage of the battery by calculating chronological engine output and brake control data for the temperature to stay within a defined range, and hence improves fuel efficiency.

    摘要： A gate driver circuit of a voltage drive type power semiconductor switching device capable of speeding up di/dt and dv/dt even during large-current driving to thereby reduce the switching loss is disclosed. This power semiconductor switching device gate driving circuit includes a drive circuit which applies a drive signal to the gate electrode of the power semiconductor switching device and a measurement unit for measuring a flow current of the power semiconductor switching device. Based on a detected value of the flow current of the power semiconductor switching device, the gate is made variable in mirror voltage thereof.

    摘要： Eddy current generated around a magnetic circuit in an MRI apparatus is one of the causes of deviation from an ideal magnetic field gradient waveform and causes image distortion, loss of strength, ghost generation, loss of signal, and spectral distortion. An object of the present invention is to suppress the generation of the eddy current. In an MRI apparatus, a ferromagnetic material formed from powder is used in a part of a magnetic circuit: the powder mainly comprising a mother phase containing iron or cobalt and showing ferromagnetism; and a high-resistance layer having a resistance not less than ten times as high as the mother phase and a Vickers hardness lower than that of the mother phase being formed in layers along parts of the surface of the powder on parts or the entire of the surface.
